2. Installation
Attention: Signal detection may be influenced by stray electric and magnetic fields from other
electrical appliances. Particularly intense disturbances are caused by computer terminals,
fluorescent tubes and ultrasonic cleaning equipment. The Q TEST 6000 therefore has to be set up
at a sufficient distance from any such appliances or devices. Paging installations, too, may disturb
signal detection.
2.1 MAINS SUPPLY
The Q TEST 6000 is supplied from the mains adapter unit with an output of 9 V~/12 VA. The
mains adapter is available for nominal mains voltages of 230 V~(range 210 V~240 V~)or 120
V~(range 110 V~ TO 130 V).
BEFORE CONNECTING THE INSTRUMENT FOR THE FIRST TIME,CHECK THAT THE
MAINS ADAPTER UNIT VOLTAGE CORRESPONDS TO YOUR MAINS SUPPLY VOLTAGE.
Use only an original Witschi mains adapter unit.
Connect the mains adapt unit to the 9 V~ socket for the mains adapter.
It takes about 3 minutes for the oven –controlled quartz time base to settle to its operational
temperature when the instrument is initially connected to the supply.
Thereafter, the quartz time base remains constantly heated as long as the instrument is remains
connected to the mains supply. The Q TEST 6000 is therefore always ready for use upon
switching on.
If the device is not going to be used for lengthy periods(e.g. during holidays),we recommend
unplugging the mains adapter from the mains supply.
2.2 PRINTER CONNECTION
Before connecting the printer (available as an option),remove the protection from the connector
printer output. The appropriate interconnection cable is supplied with the printer.
WARNING!
Before connecting the printer to the mains, check that the printer voltage
corresponds to that of your mains supply.
2.3 SWITCHING THE DISPLAY OF THE RATE FROM SEC/DAY TO SEC/MONTH
Select the required unit for rate measurements by means of the slide-switch s/day s/month on the
rear panel of the instrument.
2.4 TEST MODE SELECTION
The required test mode for the rate measurement is selected with the button in the TESTMODE
RATE field of the front panel. The selected test mode is indicated by a LED. The letter(s)
following the inscriptions by the LED’s refer to the sensor to be used.
The test mode for the module test is selected with the button in the TESTMODE MODULE field
of the front panel.
The most frequently used test modes, quartz 32 kHz and consumption  A ,are automatically
selected when the instrument is switched on.
Detailed information concerning the various test modes is given in the following sections.
2.5 TEST PARAMETER SELECTION AND SETTING
Some of the test parameters may be changed by the user.
The required parameter is selected with the button in the PARAMETER field of the front panel.
The current value of the parameter is shown by the PARAETER display. The parameter value can
be incremented or step-by step using the control knob.
All the parameters are set to the most common values and the parameter supply voltage is
displayed when the instruments is switched on.
countdown rate and countdown cons. are not variable parameters. In this case, the PARAMETER
display shows the time remaining until the end of the currently running measurement sequence.
3 RATE MEASUREMENT-GENERAL INFORMATION
3.1 PRINCIPLE OF OPERATION
The sensor picks up a signal whose period depends on the rate variation of the watch. Depending
on the test mode ,this can be the quartz oscillator frequency, the operating frequency of the
LCD-display or the running frequency of the stepping motor.
The detected signal is amplified, filtered and digitized. This signal is divide until its period
approximately corresponds to the selected measuring time. The period of subdivided signal is
measured against a highly accurate time base which serves as a reference. The difference between
the measured period and the reference period relative to zero deviation is calculated and displayed
in terms or s/day or s/month.
MEASURING PROCEDURE
The appropriate test mode is selected by means of the button in TESTMODE RATE field.
3.2
The watch is placed on the relevant sensor and, if necessary, moved or rotated until the respective
Signal LED lights up clearly or flashes in synchronism with the watch pulses.
The measurement starts automatically as soon as a watch signal is detected. The result is displayed
at the end of the measurement period. The measuring procedure continues as long as there is a
detectable signal with the result being updated at the end of each measurement period. The
transfer of a new result is indicated by a brief flashing of the display.
A currently running test sequence can be terminated and a new cycle begun at any time by
pressing the start test button.
The first measurement often provides an incorrect result because the watch was being moved at
the start of the measuring process. In case of long measuring times, we recommend re-starting the
measuring procedure once the watch has been properly positioned on the sensor. In this way the
first measurement already provides a correct result.
Should the result be outside the measuring range of 10 s/day, the result H is displayed to indicate
that the watch is running fast or L to indicate that it is running slow.
No value is displayed if the watch signal is far outside the measuring range or is disrupted that it
cannot possibly be evaluated.
No value obtained remains on the display until the end of the current measuring period even if the
watch is removed in the meantime.
TEMPERATURE EFFECTS
The rate of a quartz watch largely depends on the ambient temperature. It is therefore important
that rate accuracy measurements are executed at room temperature or the normal working
temperature on the wrist. In particular, comparative measurements must always be carried out at
the same ambient temperature.
The accuracy of the Q TEST 6000 is not influenced by fluctuations in the ambient temperature.
3.3
3.4 TESTING OF WATCHES WITH DIGITAL TRIMMING(INHIBITION)
Erroneous measurements may occur when testing watches with digital trimming if the
watchmaker is not familiar with their special characteristics which are explained below.
In the case of watches with digital trimming, the quartz oscillator frequency is not adjustable (no
trimmer). A fixed capacitor within the IC itself is so dimensioned that the oscillator frequency for
all quartzes is slightly too high. A programmable number of oscillator pulses is inhibited once per
minute( or every 20 s, 30 s or every 2, 4 or 8 minutes in the case of some watches) during
frequency division ,i.e., they are not transferred to the next divider stage.
The watch therefore runs slightly fast for 59 seconds as determined by the oscillator frequency and
extremely slowly during the second when the pulses are inhibited. The number of pulses that are
inhibited is programmed so that the mean deviation is 0.As only a whole number of pulses can be
inhibited at any one time, the adjustment is usually made in steps of 2/10 s per 24 h.
The programming of such watches is carried out by either selectively cutting traces on the printed
circuit board of the watch or by a special pulse sequence applied to the battery connections of the
IC.
If such a watch is measured by means of the quartz oscillator frequency, the result obtained
constantly shows a tendency for the watch to be fast (normally between 1 to 10 s/day).
If the watch is measured over a period of 2 s on the basis of the motor pulses or the LED
frequency, every 30 th. measurement would show a result that is extremely slow. The results of the
rest of the measurements would be fast since they correspond to the oscillator frequency.
In order to obtain a correct result, such watches have to be measured by means of the stepping
motor pulses. In this case, the measuring period has to be equivalent to the inhibition period or a
multiple of it, that is, it has to be set to 20 s, 60 s, 120 s, 240 s or 480 s respectively.
4 RATE MEASUREMENT MODES
4.1 32 kHz QUARTZ TEST MODE
The mechanical or electrical oscillations generated by the quartz oscillator are sensed directly in
the quartz 32 kHz mode. Both the acoustic and capacitive sensors are active in this mode. The
signal may also be sensed by way of the supply current.
The measuring period is 1 s and cannot be altered.
Application
This method is suitable for testing all watches with a 32 kHz quartz frequency and rate trimming
of the oscillator (which applies to practically all watches with a trimmer).
Watches with digital trimming (inhibition) produce incorrect results (very fast) with the
quartz testing method.
Sensors
The acoustic sensor (left sensor field) picks up the mechanical oscillations of the quartz crystal
which are transferred through the case to the sensor pin. The watch therefore has to touch the
sensor pin in the center of the sensor panel. The Signal quartz LED shows the intensity of the
signal received. In the event of the signal being too weak, the watch should be moved or rotated
on the sensor in order to find a better position for signal detection.
This sensor is particularly useful for watches in closed metal cases, but also be used for open
modules. The sound of the stepping motor in analogue watches may disturb signal reception and
lead to unstable results. Should such instabilities occur, the stepping motor may be stopped by
pulling out the watch crown.
The capacitive sensor (right sensor field) picks up the stray electrical field produced by the quartz
oscillator. The Signal quartz LED indicates the intensity of the signal detected. In the event of the
signal being too weak, the watch has to be moved or rotated slightly on the support , in order to
improve signal reception. The capacitive sensor is suitable for open watch module s and watches
with plastic cases. The sensor is not suitable for watches with completely closed metal cases.
If the watch is powered from the Q TEST 6000, the oscillator frequency can be filtered out of the
supply current. Rate measurement by means of the supply current only works in the  A
measuring range. Because of the numerous disturbing signals in the supply current, the
measurement may be somewhat unstable in which case a measurement by means of the motor
current pulses will give a better result.
Attention:
No other watch may be powered simultaneously if the watch is being tested on the
acoustic or capacitive sensor.
LCD TEST MODE
The LCD test mode evaluates the working frequency of the LCD-display of a watch for measuring
purposes. Any frequency may be used that is a quadruple of 4 Hz.
4.2
Application
This test mode is used for LCD watches which cannot be tested by means of quartz frequency, e.g.
watches that run at a special frequency (such as timers and calculators with a watch function) or
watches with digital trimming.
Sensor
For testing purposes, the watch is put face downwards onto the capacitive sensor (right sensor
field).
The signal LCD LED indicates the intensity of the signal received. If the signal is too weak, the
watch should be moved or rotated on the sensor to improve its position for signal detection.
Measuring time
The measuring time is normally left at the initial value of 2 s. In the case of watches with digital
trimming, this should be set to the equivalent of the inhibition period or a multiple of it.
In order to alter the measuring period, select the meas. time rate parameter and set the required
value with the rotary knob. The range extends from 2 s to 960 s.
The time left until the end of the current measurement period is indicated if the countdown rate
setting is selected in the PARAMETER field.
STEPPING MOTOR TEST MODE (stepp. motor)
The stray magnetic field or the electrical current pulse of the motor coil is sensed in this test mode.
4.3
Application
This test mode may be used for all watches with a stepping motor. It is mainly used for watches
which can otherwise only be measured with great difficulty or not at all by means of the oscillator
frequency, e.g. watches with a special quartz frequency, watches with digital trimming or for
watches where no stable result can be achieved in the quartz test mode.
Information:
Practically any analogue watch can be tested in the stepp. motor test mode with
a measuring time of 60 s, irrespective of the quartz frequency, the stepping
period or the rate trimming principle. This setting may be universally used if the
long measuring period is not disadvantageous.
sensor
The watch is placed on the magnetic sensor (right sensor field) for testing purposes. The Signal
motor LED blinks for each motor pulse, thereby indicating the signal intensity. The watch should
be moved slightly on the sensor if the signal is too weak.
Measurement by means of the current pulses
The motor pulses are filtered out of the supply when the watch is powered from the Q TEST 6000.
Rate measurement by means of the supply current only works in the  A measuring range. To
avoid the risk of other signals interfering, the magnetic sensor is automatically switched off as
long as a supply current flows.
Attention:
No other watch may be powered simultaneously if the watch is being tested on
the magnetic sensor.
Measuring period
The measuring period has to correspond to the period of the stepping motor or a multiple of it.
Watches with digital trimming (inhibition) have to be measured over an inhibition period or a
multiple of it .The initial setting of 2 s is suitable for watches with 1 s steps and a trimmer. A
setting of 60 s is correct in most cases for inhibition watches.
In order to alter the measuring period, select the meas. time rate parameter and set the required
value with the rotary knob. The range extends from 2 s to 960 s.
The time left until the end of the current measurement period is indicated if the countdown rate
setting is selected in the PARAMETER field.
MECHANICAL TEST MODE (mechanical)
In this test mode, the sound of the movement in a mechanical watch is evaluated for rate
measurement purposes. Results are indicated in s/day.
4.4
Application
Mechanical watches running at 18000, 19800, 21600, 28800, or 36000 beats per hour may be
tested with the Q TEST 6000. The instrument is ideally suitable for rapid testing of mechanical
watches and may also be used for adjustment purposes. For trouble shooting and repairs, however,
we recommend the use of an instrument with graphical recording (e.g. the WATCH EXPERT).
Sensor
The watch is placed on the acoustic sensor for testing purposes. The watch case has to touch the
sensor pin. The Signal LCD LED indicates the signal intensity.
Measuring period
The measuring period is 4 s and cannot be changed.
TUNING FORK TESTMODE (tuning fork)
The stray magnetic field of the tuning fork oscillator is sensed for tuning fork watches in this test
method. Results are indicated in s/day.
4.5
Application
The watch is placed on the magnetic sensor for testing purposes. The Signal motor LED indicates
the intensity of the signal received. The watch has to be moved around on the sensor field until an
optimal signal intensity is achieved.
Measuring period
The measuring period is 4 s and cannot be changed.
SPECIAL PROGRAMS FOR PROGRAMMABLE ICs (special program)
Various IC’s can be programmed or be quickly tested through the supply current.
1 Set the voltage to 1.55V in the PARAMETER field with supply voltage.
2 Select special program in the PARAMETER field. Use the rotary knob to set the program
number, making absolutely sure that it is the correct number for the particular IC. The number
is shown on the PARAMETER display. Any of the following numbers can be chosen:
P 1 for Philips IC’s series PCA 1400
P 2 for Philips IC’s series PCA 1460-1600
P 3 for MEM IC’s series H-1138,H-1140,H-1238,H-1138,H-1538
P 4 for MEM IC’s series H-1221,H-5222 SPL
3 Select quartz 32 kHz in the TESTMODE RATE field.
4 Make contact to the watch movement or electronic module by means of the movable probe
arms. If a module holder type PM 6000 or a dummy battery is connected to the instrument, the
watch movement can be powered alternatively through either of these.
5 Once the movement has been connected, check that the Signal quartz LED has lit up in and
that the frequency is shown on the RATE display. In the event of the signal being too weak
(unstable or no rate display at all), select stepp. motor in the TESTMODE RATE and set meas.
time rate in the PARAMETER field.
6 Accelerated test. Briefly press and then release the start test button in the TEST CONTROL
field. The rate of the movement will now be displayed for a few seconds.
7 Program and test the IC. Simultaneously press the buttons start test and print result for about
2-3 seconds and then release both of them. The IC will be newly programmed, tested and the
rate of the movement displayed for a few seconds.
The module cannot be adjusted precisely to 0 since the adjustment is normally carried out in steps
of 0.2 s. Adjustment is made as close as possible to 0 but always remains in the positive value
range.
5 CURRENT CONSUMPTION MEASUREMENT
5.1 GENERAL INFORMATION
The current consumption of a watch provides information about the expected life of the battery
and is an important quality criterion for quartz watches.
4.6
In the case of analogue watches, the current is a combination of the IC current in the range of a
few 100 nA and peak loads during motor pulses of up to 1mA. The Q TEST 6000 registers the
entire current by summing all portions of the current flow throughout the measuring period
(integrating measurement). The result of this measurement provides the mean value of the entire
current consumption (IC current and motor current) throughout the measuring period.
The stepping motor can be switched off by pulling out the crown (possible with most watches) if
only the IC current is to be measured.
The manufacturer’s data should be consulted for the maximum permissible current consumption
of a watch.
Generally, the current consumption of the watch should be lower the smaller the battery is.
The typical current consumption of modern quartz watches amounts to between 1 and 2 μA for
analogue watches with 1 s/step and for watches with longer stepping periods 0.5 up to 1.0μA.
5.2 CONTACT TO THE WATCH
To measure the current consumption and the minimum working voltage, take the battery out of the
watch and power it from the Q TEST 6000 instead.
To make contact with the watch, fix it in the module holder and place it on the glass window of
the Q TEST 6000. The movable probe arms should be set to the points to be contacted and pressed
down far enough to depress the telescopic probes by about 1mm. The probes should be grasped at
their rear ends to adjust the height.
The red positive(+) probe is placed on a point normally connected to the positive pole of the
battery (battery case). The entire bottom plate is connected to the positive pole in most watches.
The black negative (-) probe is placed on a point normally connected to the negative pole of the
battery (battery lid). The contact spring for the negative battery connection is usually the most
accessible point in the majority of watches.
The two LED’s open and short give an immediate indication of having made successful contact.
Both LED’s are extinguished as soon as correct contact has been established. If the circuit is open,
the open LED lights up. The short LED lights up in the case of a short circuit or wrong polarity.
The watch hands can be observed in the mirror below the window. If the watch runs the contacts
are in order.
Although the maximum supply current is limited to 3mA in the μA range, the
watch may be damaged by contacting the wrong points or applying the wrong
polarity.
In the case of clocks, the module supply is best connected with the help of the measuring leads
and crocodile clips.
Attention:
5.3 SUPPLY VOLTAGE
When the supply voltage parameter is selected, the PARAMETER display indicates the voltage at
the test socket, which may then be changed within the range from 0 to 3.5 V by turning the knob.
Current consumption measurements should be effected with the nominal battery voltage which has
the following values for the various battery types:
Silver oxide battery (standard watch battery):
Mercury cells (old battery type):
Lithium battery 2.0 V type:
Lithium battery 3.0 V type:
Zinc-carbon or alkali battery (for clocks):
1.55 V
1.35 V
2.10 V
3.00 V
1.40 V
5.4 MEASURING PERIOD
To ensure an accurate measurement of the mean current consumption, the measuring period in the
case of analogue watches has to be equivalent to a stepping period or a multiple of it.
The currents for the positive and negative motor pulse are often unequal which can cause small
fluctuations when the measuring time is only based on a single stepping period.
A measuring time of 1 s is sufficient for LCD watches.
To set the measuring period, select the meas. time cons. parameter and set the measuring period to
the required value by means of the adjustment knob. The range extends from 1 to 60 seconds.
The time left until the end of the current measurement period is indicated if the countdown cons.
setting is selected in the parameter field of the front panel.
5.5 THEμA MEASURING RANGE (consumption μA )
consumption μA consists of the 100μA (10 nA resolution) and 1000 μA (100μA resolution)
measuring ranges with automatic range selection. Peak loads of up to 2 mA may be correctly
measured in this test mode. Current limitation limits the maximum supply current to about 3mA.
Application
The current consumption of any type of quartz watch can be measured in this test mode. Rate
measurement by means of the supply current is possible only under these circumstances.
Neither lamps for LCD-displays nor alarm buzzers may be operated in this test mode.
5.6 THE mA MEASURING RANGE (consumption mA)
consumption mA consists THE 10 mA (1 μ A resolution) and 20 mA(10 μ A
resolution )measuring ranges. The maximum supply current is limited to about 50 mA.
Application
Measurement of the current consumption of watch alarms and lamps for LC-displays. Rate
measurement by means of the supply current is impossible in this test mode.
6
STARTING VOLTAGE
The minimum operating or starting voltage is an indicator of the power reserves of the watch and
the capacity to continue running in spite of an almost exhausted or heavily loaded battery (LCD
watches with the light switched on).
In order to measure the starting voltage, supply power to the watch as explained in Section 5.
While observing the hands of the watch in the mirror, reduce the supply voltage until the watch
stops, then slowly increase it once more until the watch starts running again.
Normally it is sufficient to check that the watch runs correctly at .a reduced supply voltage. The
minimum supply voltage usually in the order of 1.25 V in the case of watches with a silver oxide
battery.
7
BATTERY TEST
7.1 GENERAL INFORMATION
The voltage of a watch battery remains constant almost to the end of its life and only drops when
it is fully run down. The test, even under load, only shows whether the battery is still usable or
entirely exhausted. No information concerning the remaining battery life can be derived.
The battery should also be checked for leaks during the test. The battery must be replaced if salt
crystals are visible between the case and lid even though the voltage may still be high enough.
The polarity of the battery must be observed when testing. Generally speaking, the case of a
battery for a wrist watch is normally the positive (+) pole and the lid is the negative (-) one.
Conversely, the case serves as negative pole and the contact on the lid as the positive one for clock
batteries and lithium batteries.
For testing purposes, the battery has to be placed on the battery support in the BATTERY TEST
field on the front panel with its positive side downwards and contacted at the negative pole by the
black test probe or the black measuring lead.
The battery may also be checked directly in the watch with the help of the measuring leads.
The measured battery voltage is displayed in the MODULE panel field.
7.2
BATTERY LOAD
Loading the battery with a load resistor whether it can supply the necessary current without the
voltage dropping out of tolerance.
The basic load without activating any buttons amounts to about 2μA. This load corresponds
approximately to the current consumption of a watch. The battery should not show any substantial
voltage drop.
A load of 1kΩcan be switched on by pressing low drain button. This load corresponds
approximately to the peak load during a motor pulse.
A load of 100Ω may be added by pressing the high drain button. This load corresponds
approximately to the current drawn when the light in an LCD watch is activated. The 100Ω load
is only practicable for high drain and clock batteries. The button should not be pressed for longer
than necessary otherwise the battery will be quickly drained.

RESISTANCE MEASUREMENT
8.1 GENERAL INFORMATION
The resistance measuring range is predominantly used for the location of open or short circuits in
the motor coil of analogue watches or insulation defects between coil and coil core or mounting
plate.
Resistance measurements are also useful for continuity and insulation testing of connections,
circuits and switches.
The measurement is made with a constant voltage of 0.3 V. With this low test voltage, components
which are connected to an integrated circuit can also be checked without falsifying the result. The
measuring range extends from 15Ω to 5 MΩ with automatic ranging.
The battery has to be taken out of the watch for all resistance measurements.
Contact to the measuring points is effected by using the movable probe arms or measuring leads.
8.2 COIL RESISTANCE AND COIL INSULATION
Coil resistance
The two coil connections on the watch module are contacted for the measurement of coil
resistance. Polarity in unimportant.
The resistance value in the case of analogue watches is normally between 1kΩ and 3kΩ. Please
consult the watch manufacturer’s data for more precise values.
A break in the coil is indicated by the H display and by the open LED lighting up.
Insulation
one of the two coil connections and the mounting plate of the watch have to be contacted to test
the coil insulation. A break is indicated if the insulation is good (H display and the open LED
lights up). A low resistance value is indicated in the case of defective insulation.
8.3 CONTINUITY AND INSULATION TEST
Observation of the two LED’s, short and open, suffices for continuity and insulation tests on
arbitrary watch components.
If the short LED lights up the two test points are interconnected and if the open LED lights up
they are insulated from one another. The resistance value may be read on the display if there is no
LED signal.

PULSE GENERATOR
9.1
APPLICATION\
The stepping motor and the mechanical parts of analogue quartz watches can be tested
independently of the IC in the pulse generator test mode.
The pulse generator supplies bipolar pulses with adjustable voltage and pulse width. The pulse
repetition frequency is either 8 or 16 Hz depending on the pulse width selected.
The battery has to be taken out before the test is carried out. The watch is fixed in the module
holder and placed on the glass window. The coil connections are contacted with the two probes.
Correct operation of the watch can be checked in the mirror.
The pulse generator function provides no numerical results.
9.2 PARAMETER SETTING
Pulse voltage
The pulse voltage can be set when the supply voltage parameter is selected. Under normal
conditions , the pulse voltage is 0.1 to 0.2 V lower than the actual battery voltage due to the
voltage drop across the output transistors. The pulse voltage should be appropriately adjusted to
ensure that the operation with the pulse generator is subject to the same conditions.
Pulse width
Select the pulse width parameter to set the pulse width which can be adjusted with the rotary knob.
The PARAMETER display window shows the pulse width in ms. The pulse frequency is 16 Hz
for pulse widths below 16 ms and 8 Hz for those above 16 ms.
The correct pulse width has to be set to accord with the data from the watch manufacture. The
standard pulse width of 6.8 ms may be taken for a simple function test if the correct pulse width is
not known.
Chopped pulses
The pulse generator in the Q TEST 6000 supplies no chopped pulses. Such pulses can, however,
be simulated to a large degree by reducing the pulse voltage in proportion to the chopp ratio.
10 ALARM TEST
The Q TEST 6000 supplies a test frequency of 2 kHz in the alarm test mode to test the magnetic
or piezoelectric alarm buzzer in a watch.
The voltage can be set with the supply voltage parameter.
11 TROUBLE SHOOTING FOR QUARTZ WATCHES
The following notes contain some recommendations to watchmakers, on how to locate defects in
quartz watches both quickly and reliably.
11.1 SYSTEMATIC TROUBLE SHOOTING
Proceed as follows to localize a defect quickly in a quartz watch that is not running:
• Place the watch on the acoustic sensor and check to see whether any signal exists (quartz LED
lights up). Check the battery if there is no signal.
• If the battery is found to be in order and the quartz signal is indicated, test the resistance and
insulation of the motor coil.
• If the coil is in order, place the watch on the magnetic sensor and check whether there are any
motor pulses (motor LED lights up with each pulse).
• If the watch passes all of the above checks, there must be a mechanical defect, such as: hands
catching, blocked or extraneous matter in the movement, fine steel particles on the rotor
magnet, etc.
11.2 BATTERY
Whatever the defect, check the battery first (see Sections 7-7.3). Remove any dirt or oxidation
from the battery contacts and bend the contact springs back into shape as necessary.
11.3 IC DEFECTS
Oscillator test
In the quartz 32 kHz test mode, the quartz LED shows whether the quartz oscillator is functioning
and whether the 34 kHz signal is present. If no signal is displayed, either the quartz crystal, the
trimmer or the integrated circuit (IC) is defective.
Testing the motor driver stage
The motor LED lights briefly with each motor pulse in the consumption μA test mode. If there
is no signal in spite of the fact that the motor coil is in order, then the following applies:
• either the IC is defect, or
• the reset remains activated although the hands setting stem is pressed in (defective mechanism,
stem too short).
11.4 MECHANICAL DEFECTS
If a watch runs very slow or does not run at all, although the electronic module and motor coil are
perfectly operational, the cause is to be sought in the mechanics of the watch. Possible defects are:
• Steel particles adhering to and blocking the rotor magnet. Small chips can be set free as the
case bottom is screwed or snapped on.
• The mechanism does not run freely or is completely blocked. Small particles in the gears may
partially or even entirely block the movement. Test for free running and cleanliness.
•
•
Check whether the hands catch, or touch the glass or face.
The “reset by stem” mechanism is defective. When the hands setting stem is pulled, the
seconds hand is mechanically blocked and the reset contacted. The mechanism should not
touch the seconds gear wheel when the hands setting stem is pressed in and the reset contact
must be opened. This fault occurs if the mechanism is defective or the stem is too short.
11.5 LCD-DISPLAYS
No display on an LCD watch.
• First test the battery.
Place the watch on the acoustic sensor and select the quartz 32 kHz test mode.
• If the quartz LED does not light up, either the quartz crystal, the trimmer or the IC is
defective.
• If the quartz LED lights up, the IC or the display is defective.
The LCD display lacks several segments.
Possible faults:
• Insufficient contact between the printed circuit and the display; carefully clean the contact
pads and contact strips;
• IC or display defective.
12 PM 6000 MODULE HOLDER
The PM 6000 module holder is an accessory for the serial testing of watches. It does not belong to
